Peer-to-Peer Applications

Here is a list of P2P Applications for the research and education communities. This is an initial attempt to collect and identify such applications. So, please use the form below to submit any P2P applications we may have missed in this list.

Research Applications

• Intel® Philanthropic Peer-to-Peer Program [http://www.intel.com/cure/] -- "Intel’s Philanthropic peer-to-peer program links millions of PCs to create a computing resource for researchers in a wide-variety of fields. For example, Leland Stanford Junior University is focusing on protein folding and related diseases such as Alzheimer’s, ALS and Parkinson’s."
• SETI@home [http://www.seti.org/science/setiathome.html] -- "The SETI@home project links and uses donated computer processing capacity to analyze data collected from a radio telescope located in Puerto Rico."
• Worldwide Lexicon Project [http://picto.weblogger.com/] -- "The worldwide lexicon project is an open source initiative to create a multilingual dictionary service for the Internet, and to create a simple, standardized protocol for talking to dictionary, encyclopedia and translation servers throughout the web. Similar to the SETI@Home project. While SETI@Home taps the idle CPUs of millions of personal computers, the worldwide lexicon enlists the help of internet users who are logged in, but not busy. Think of this as distributed human computation."

Educational Applications

• eduCommons [http://www.educommons.org/]-- The eduCommons is an open system for creating, sharing, and reusing educational content and discourse to support people's learning. [more info]
• Edutella [http://edutella.jxta.org/] -- "Edutella is a peer-to-peer service for the exchange of educational metadata. Edutella lives on top of the Semantic Web framework as a distributed query and search service."

General Applications

• Chord Project [http://www.pdos.lcs.mit.edu/chord/] -- "The Chord project aims to build scalable, robust distributed systems using peer-to-peer ideas."  
• Groove Networks [http://www.groove.net] -- "Groove Networks has developed software tools that provide multiple users realtime access to information simultaneously. Developed by the creator of Lotus Notes, Groove has strong backing from a variety of partners including Microsoft."
• JXTA [http://wwws.sun.com/software/jxta/] -- "Sun Microsystems Project JXTA is a set of peer-to-peer protocols that allows any connected device (cell phone to PDA, PC to server) to communicate and collaborate. Potential scenarios for JXTA include allowing multiple machines that are not part of the same network access the same files."
• LOCKSS [http://lockss.stanford.edu/] -- "Stanford University Library Systems LOCKSS (Lots of Copies Keeps Content Safe) project aims to create a "low-cost, persistent digital caches" of e-journal content. LOCKSS has active support of the librarian and publishing community and is currently moving beyond beta testing stage."
• The Metadata3 Project [http://www.md3.org] -- "The Metadata3 project (also known as md3) is a peer-to-peer application that provides access to quality metadata, and the ability to translate between different metadata schemes at the semantic, structural, and/or syntactical layers. "
• OceanStore Project [http://oceanstore.cs.berkeley.edu/info/overview.html] -- "OceanStore is a global persistent data store designed to scale to billions of users. It provides a consistent, highly-available, and durable storage utility atop an infrastructure comprised of untrusted servers. Any computer can join the infrastructure, contributing storage or providing local user access in exchange for economic compensation."
• Piazza [http://data.cs.washington.edu/p2p/piazza/] -- "The vision of the Piazza peer data management system (PDMS) project is to provide "semantic mediation" between an environment of thousands of peers, each with its own schemas. Rather than requiring the use of a single, uniform, centralized mediated schema to share data between peers, Piazza allows peers to define semantic mappings between pairs of peers (or among small subsets of peers). In turn, transitive relationships among the schemas of the peers are exploited so the entire resources of the PDMS can be used."
• Publius [http://publius.cdt.org/] -- "Publius is a Web publishing system that is highly resistant to censorship and provides publishers with a high degree of anonymity."
• Tapestry [http://www.cs.berkeley.edu/~ravenben/tapestry/] -- "Tapestry is an overlay location and routing infrastructure that provides location-independent routing of messages directly to the closest copy of an object or service using only point-to-point links and without centralized resources."
